How to restrict inbound and outbound internet e-mail traffic from and to active directory group

We pretend to allow only a list of inbound/outbound emails address to an Active Directory Group.

It's factible in a Exchange 2003 scenario?

user@mydomain.com will permit only e-mails from user@partner.com, user@partner2.com
user@mydomain.com will send e-mails only to user@partner.com, user@partner2.com

This users are grouped in Active directory.  The contacts of partners exists in AD

any suggestion?

On the Exchange General tab for the DL and Contacts you can set which accounts it can receive from.  Just add such accounts to that listbox.

I've set as is shown in the attached file
It started to work for inbound email after MSExchangeSA service was restarted.

But how i tell Exchange to send email only to a list, there is no setting here to "Deliver only to"

So you want to setup an account that can only send to particular addresses?  I'm not sure that is possible.

I thought you were trying to restrict the sending to a DL and to Contacts.  Both, the DL and the Contacts will have the properties window in your screenshot so you can restrict who can send to them.

For Outbound filtering:
- We set a Outbound Rule in the gateway antispam server (Symantec Mail Security for SMTP)
- We apply the action of delete the message when it came from "Restricted Outbound Users" LDAP Group in sync with AD GC
- We set a exception when Recipient Envelope has one of the authorized domains
- It cannot be set user by user, but the outbound rule applies for any LDAP group, so i can restrict some groups with only one member.
- I can apply authorized domains o specific e-mail addresses for any LDAP Group

For Inbound Filtering:
robrandon and the suggestion stated was perfect.
- we also need to permit internal mails and some external contacts only so we cannot mark "Authenticated Users Only"
- we created a Exchange Query Based Group with all internal users in a LDAP Query and we added it to the dialog box "only from"

that's all
